Ben, is the kernel source package also updated? I'm running a kernel without preemption and with a larger stack size, because of ndiswrapper. My wifi card is (or was) very flaky with the stock kernel. But the source package reported itself as 2.6.15-9 even when the binary was up to 2.6.15-23. -- Hang while booting https://launchpad.net/bugs/32597
